The electronic cigarette comprises a cigarette cartridge and a battery device, wherein the cigarette cartridge is detachably connected with the battery device, the battery device is provided with a heating part, a detection assembly and a controller, when the cigarette cartridge is dismounted from the battery device, the detection assembly generates a separation signal, and the controller is used for controlling the heating part to work according to the separation signal so as to remove residues on the heating part. The invention can automatically remove the residues on the heating element when the cigarette cartridge is detached from the battery device, thereby prolonging the service life of the heating element and the electronic components in the battery device.

The method for controlling the electronic cigarette according to the above embodiment will be described in detail below.

Figure 20 is a flow chart illustrating a method of controlling an e-cigarette in an exemplary embodiment of the invention. As shown in fig. 20, the method for controlling an electronic cigarette of the present embodiment includes, but is not limited to, the following steps:

step S1, detecting a separation signal generated when a cartridge is detached from a battery device, wherein aerosol-forming substrates are stored in the cartridge, and a heating element is arranged on the battery device and used for heating the aerosol-forming substrates in the cartridge when the battery device is electrified;

and S2, controlling the heating element to work to remove residues on the heating element when the separation signal is detected.

The battery device is provided with a heating element, the heating element is used for heating the aerosol-forming substrate in the cartridge to form smoke when the battery device is electrified, when the cartridge is detached from the battery device, the liquid absorbing element is separated from the heating element, residues left in the using process can be attached to the heating element, and the residues are the aerosol-forming substrate left on the heating element or other carbides formed after heating. In one embodiment, the aerosol-forming substrate is a liquid, and the cartridge is provided with a corresponding wicking element for supplying the liquid to the heat generating element, the wicking element being in contact with or in close proximity to the heat generating element when the cartridge is mounted on the battery device, so that the liquid stored in the cartridge can be supplied to the heat generating element for atomization.

In one embodiment, when the battery device is provided with the first sensor and the second sensor corresponding to the first embodiment, the step S1 of detecting the separation signal generated when the cartridge is removed from the battery device includes:

acquiring a first airflow signal of a first sensor and a second airflow signal of a second sensor, wherein the first sensor is arranged in a first cavity on a battery device, the second sensor is arranged in a second cavity on the battery device, the first cavity is communicated with an airflow channel of the electronic cigarette and is isolated from the second cavity, and the second cavity is in a closed state when the cartridge is mounted on the battery device and is in an open state after the cartridge is dismounted from the battery device;

The first sensor is arranged in a first cavity on the battery device, the second sensor is arranged in a second cavity on the battery device, the first cavity is communicated with an airflow channel of the electronic cigarette, the first cavity and the second cavity are not communicated with each other and are isolated from each other, the second cavity is in a closed state when the cigarette cartridge is installed on the battery device and is in an open state after the cigarette cartridge is removed from the battery device, in practical implementation, a sealing part is arranged on the cigarette cartridge, the sealing part is inserted into an opening of the second cavity and blocks the opening when the cigarette cartridge is installed on the battery device, therefore, when the cigarette cartridge is removed from the battery device, the second cavity generates negative pressure due to the extraction of the sealing part, the second airflow signal of the second sensor is a high-level signal, meanwhile, the user can not suck when removing the cigarette cartridge, namely, no airflow passes through the airflow channel of the electronic cigarette, the air pressure in the first cavity can not change when the cigarette cartridge is extracted, therefore, the first airflow signal of the first sensor is a low-level signal, the second airflow signal is a high-level signal, and the battery device can be considered as a high-level signal when the cigarette cartridge is removed from the battery device.

When detecting the separation signal, the electron cigarette control generates heat the piece and carries out work in order to clear away the residue on the piece that generates heat. During actual implementation, the electronic cigarette controls the heating part to work according to preset parameters, so that the self-cleaning mode is started to clear residues on the heating part. Wherein, the preset parameter includes preset working voltage, preset temperature and preset power one of them and preset operating duration, preset working voltage is greater than the working voltage when the electron cigarette is in the suction state, preset working voltage can also be equal to the current output voltage of the battery, preset temperature is greater than the working temperature when the electron cigarette is in the suction state, the working temperature is the atomization temperature when the heating element normally works, preset power is greater than the working power when the electron cigarette is in the suction state, the working power is the atomization power when the heating element normally works, through adopting higher working voltage, working temperature or working power, can consume the adherent residue fast in a shorter time, preset operating duration is a shorter duration, for example, 1 second. Of course, in practical implementation, the heating element is controlled to work according to the corresponding working parameters when the electronic cigarette is in a smoking state, and residues on the heating element can be removed, and the difference is only that the removal time is different.

When the battery device is provided with the first sensor and the second sensor respectively located in the first cavity and the second cavity, the control method of the electronic cigarette may further include the following steps:

If the first airflow signal and the second airflow signal are both low level, it indicates that the electronic cigarette is in an idle state, and the heating element does not work. When the electron cigarette was smoked under the condition of not installing the cigarette bullet, all had the air current to pass through in first chamber and the second chamber, first air current signal is the high level with second air current signal, if children acquire the electron cigarette and face the electron cigarette suction this moment, then the work of the control piece that generates heat can cause the scald, consequently, when first air current signal is the high level with second air current signal, the piece that generates heat is out of work.

and if the first airflow signal is at a high level and the second airflow signal is at a low level, controlling the heating element to work according to corresponding working parameters when the electronic cigarette is in a smoking state.

When a user sucks the electronic cigarette, airflow passes through an airflow channel of the electronic cigarette, an airflow signal generated by the first sensor is high level, whether the cigarette cartridge is in an installation state currently is judged by combining the airflow signal of the second sensor, when the user sucks the electronic cigarette, the second sensor cannot detect airflow change only when the second cavity is in a closed state, and therefore the second cavity is in a closed state and the cigarette cartridge is installed on the electronic cigarette. Therefore, when the first airflow signal is at a high level and the second airflow signal is at a low level, it indicates that the cartridge is installed and the user is smoking, and at this time, the electronic cigarette controls the heating element to operate according to the corresponding operating parameters when the electronic cigarette is in a smoking state, that is, controls the heating element to perform normal atomization operation.

After the heating member is controlled to work according to the corresponding working parameters when the electronic cigarette is in the smoking state, the control method of the electronic cigarette can further comprise the following steps:

if the time length for increasing the resistance value of the heating element to the preset resistance value is less than the preset time length, controlling the heating element to stop working;

if the time length of the resistance value of the heating element rising to the preset resistance value is larger than or equal to the preset time length, the output power of the heating element is controlled, and the resistance value of the heating element is kept at the preset resistance value.

Wherein, predetermine the resistance and carry out the atomizing resistance of atomizing during operation for the electron cigarette, for normal operating resistance, generally, an atomizing temperature can be set for to the electron cigarette when dispatching from the factory, this atomizing temperature corresponds a resistance that generates heat, the electron cigarette is at the during operation, battery device makes the resistance that generates heat a work and real-time supervision piece that generates heat to a piece output voltage that generates heat, when the resistance that generates heat reaches the resistance that preset atomizing temperature corresponds, through control output, make the resistance of the piece that generates heat stable at this resistance, also be aforementioned atomizing resistance, of course, the atomizing resistance also can be calculated according to user actual set's atomizing temperature or power and obtain.

When the separation signal is detected, the electronic cigarette controls the heating piece to work so as to clear away residues on the heating piece. During actual implementation, the electronic cigarette controls the heating part to work according to preset parameters, so that residues on the heating part are cleared away. The preset parameters comprise preset working voltage, one of preset temperature and preset power and preset duration, the preset working voltage is greater than the working voltage of the electronic cigarette in the suction state, the preset working voltage can also be equal to the current output voltage of the battery, the preset temperature is greater than the working temperature of the electronic cigarette in the suction state, the working temperature is the atomization temperature of the heating element in normal operation, the preset power is greater than the working power of the electronic cigarette in the suction state, the working power is the atomization power of the heating element in normal operation, by adopting higher working voltage, working temperature or working power, the attached residues can be quickly consumed in shorter time, for example, the preset working duration is shorter duration, for example, 1 second. Of course, the heating element is controlled to work according to the corresponding working parameters when the electronic cigarette is in the smoking state in actual implementation, and residues on the heating element can be removed.

When the battery device is provided with the state detection circuit and the third sensor, the control method of the electronic cigarette may further include the following steps:

and if the third airflow signal is at a high level, controlling the heating piece to work according to the corresponding working parameters when the electronic cigarette is in a smoking state.

When the on-off signal of the state detection circuit on the battery device is the conduction signal, the electronic cigarette confirms that the cartridge is in the installation state, and whether the user is sucking or not is judged according to the airflow signal of the third sensor at the moment. When the user smoked the electron cigarette, there was the air current to pass through in the air current channel of electron cigarette, and the air current signal that the third sensor produced is the high level, and at this moment, the electron cigarette produced heat according to the operating parameter control that corresponds when the electron cigarette was in the suction state and produces heat the piece and carry out work, also controls to produce heat the piece and carry out normal atomizing work promptly. It will be appreciated that upon detection of a detach signal indicating removal of the cartridge from the battery means that the cartridge is removed and in an uninstalled condition, the operation of the heat generating element is not controlled even if the third airflow signal is detected to be high.

if the time length of the resistance value of the heating part rising to the preset resistance value is larger than or equal to the preset time length, the output power of the heating part is controlled, and the resistance value of the heating part is kept at the preset resistance value.

Wherein, predetermine the resistance and carry out the atomizing resistance of atomizing during operation for the electron cigarette, for normal operating resistance, generally, an atomizing temperature can be set for to the electron cigarette when dispatching from the factory, this atomizing temperature corresponds a resistance that generates heat, the electron cigarette is at the during operation, battery device makes the resistance that generates heat a work and real-time supervision piece that generates heat to a piece output voltage that generates heat, when the resistance that generates heat reaches the resistance that preset atomizing temperature corresponds, through control output, make the resistance of the piece that generates heat stable at this resistance, also be aforementioned atomizing resistance, of course, the atomizing resistance also can be calculated according to user actual set's atomizing temperature or power and obtain. In the heating process of the electronic cigarette, if the time for increasing the resistance value of the heating part to the preset resistance value is shorter than the preset time, the heating part is heated too fast due to dry burning, and the heating is stopped at the moment for protecting the cigarette cartridge; if the time length of the resistance value of the heating element rising to the preset resistance value is longer than or equal to the preset time length, the heating element works normally, at the moment, the output power of the heating element is controlled, so that the resistance value of the heating element is stabilized in the preset resistance value, and the stable resistance value means that the deviation of the resistance value of the heating element relative to the preset resistance value is in a smaller range.

In an embodiment, the method for controlling an electronic cigarette may further include the steps of:

if the resistance value change rate is less than the preset change rate, controlling the heating part to stop working;

if the resistance change rate is larger than or equal to the preset change rate, the heating element is controlled to work so as to remove residues on the heating element.

The electronic cigarette is characterized in that a self-cleaning manual button is further arranged at the bottom of the electronic cigarette, when the manual button is pressed, a preset operation signal for controlling the heating piece to work is generated, and the heating piece starts to heat to perform self-cleaning. The preset change rate refers to the resistance change rate when the heating part works to remove the residue under the condition that the cartridge is not installed, and when the heating part works to remove the residue with preset parameters, the preset change rate refers to the resistance change rate when the heating part works with preset parameters under the condition that the cartridge is not installed. In the self-cleaning process, if the cigarette cartridge is still inserted into the electronic cigarette, the resistance change rate of the heating part is smaller than the preset change rate due to the fact that more aerosol forms the substrate attached to the heating part, at the moment, if the cigarette cartridge is damaged by continuous self-cleaning, the heating part is controlled to stop working and stop self-cleaning for ensuring the good condition of the cigarette cartridge, otherwise, if the resistance change rate is larger than or equal to the preset change rate, the heating part is considered not to be in contact with the aerosol in the cigarette cartridge to form the substrate, residue cleaning can be carried out, and at the moment, the heating part is continuously controlled to work.
